To all ywhom it may concern:

Be it known that I, Daniel. F. CAR anonimi., a citizen of the United States, residing at Minneapolis, in the county 'of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Combination-Locks; and I do hereby declare the following tol be a full, clear, and exact description of the invention, such as will-enable'others skilled in the art to which it appertains to make and use the same.

My invent-ion relates, broadly, to permutation or combination locks, but more particularly, to that type wherein various Inovenients necessary to work the proper combination are effected by manipulation of a single knob or manually operated actuator. The present lock is a radical departure from th'e well kn'own rotary tumbler lock, in that the knob or actuator is not mounted for simple rotary motion, but iscapable of movement in any one of several different directions. Generally stated, however, the lock is capable of universal use wherever relatively movable parts will be locked together and released, or circuit connections are to be controlled.

The accompanying drawings illustrate the lock mechanism proper in what is believed to be its preferred forni and several different applications of this lock mechanism are also illustrated.

Referring to the drawings, wherein like `characters indicate like parts throughout the several views,

Fig. 23 is a detail in horizontalsection on Fig. 25 is a diagrammatic'vertical section 'illustrating the lock, Figs. 2-1' to 24, as applied to an automobile.

Referring first to the construction and arp rangement illustrated in Figs. 1 to 15,*i`nclusive, the numeral 2i, indicates the base and. the numeral 27 the removable shell of the lock casing. Ptigidly secured to the base 26 within the shell 27 is a skeleton-framework 28 which comprises as its chief element, a' skeletonized top plate 28B, but lalso comprises' other bearingsand featnres'which will'be' hereinafter noted. As shown', the shell'27 is arranged vto be .locked directly to latch plate 30- adjustably attached to the plate 28a. as

shown in Figs. 11 and 13, andhence,is directly loclred to 'the base 26, by a latch device best shown in Fig. 3 but also indicated in Figs. 11, 12 and 13, which latch device comprises a depending; beveled nose book lug 29 on the inside of the said shell 27 and. a

' coperating spring-held latch plate 30 slid ably mounted on the said plate 28%,which latch plate 30 is operated by'movement of. the piston 76 against the lever 74 when lever- 74 has been broughtl into proper relative position by operation of the stud 73 on'disk 54.

necesite ing dog 37 at the time and under conditions hereinafter noted. For temporarily holding the retaining dog 37 in a 4released position, under conditions hereinaftennote'd," a light spring latch arm 40 (see Figs. 14 and 15) is anchored vatone end to bearing arm36, and

at its free end has a shoulder 40l that is y engageable with a shouldeix'37b of said re taining9 dog.

The gear 32 has a depending cam,lug or myV stud 32a that islengageable with an upi wardly bulged cam-actingportion .of `thelatch .40.' to release. thesame from said' dog',

4gather and are mounted'on common shafts' 43, and, inasmuch as the, gears 32 and 34 are 'beveled gears, the lsaid gears 41'and 42 are Rigidly secured to and proj ecting from the base 26 is a stud 31 on which is a sleeve that connects for common rotation an upper beveled gea-r 32 and lower spur gear 33, and upon which sleeve is loosely j ournaled a beveled gear 34.

The numeral, 35 indicates anvannular bearing plate secured by suitable legs to the base 26 and surrounds the loose beveled gear 34 with ample clearance. A small bearing arm or bracket 36 is rigidly secured to the plate 35 and projects radially inward between the two bevel gears 32 and 34. The said gear 32 is made hollow and is thus formed with a cylindric-al inner surface that is engaged frictionally by a frictional retaining doglr 37 (see particularly Figs. 6 and`14), that is pivoted to the inner end of the said arm 36 and is provided with a long curved tail 37a. A coiled 'spring 38 suitably anchored to the base, and7 as shown, connected to the troc v end of the tail 37a by a link 38a. normallyr holds the retaining dog 37 in trictionnl on gagement with the copcratlng suriacc oi the beveled gear 32. Hence. normally. thc

also beveled gears. 'The gears 42 are rigidly secured to lower end portions of oblique shafts 43, and the gears 41 are loosely journaled on the same shafts. The oblique shafts 43 standin planes that radiate from the axis ofl the fixed stud 31, and at their lower ends, they are journaleld inl bearings 355 on'the annular bearing plateI 35, while their upper ends-'they'are journaled in bear ings 44a of a bracket 44 which-is rigidly se cured to one 'of the end Walls or platee of the frame 28.

Small ratchet Wheels or segments 45 are rigidly secured to the upper end portions of the oblique shafts 43. The gears 41 are provided with sleeve-like hubs, upon ,which camlike so-called tumblers, 46 are lrigidly, but adjustably secured by set screws, or otherwise. Spacing Washers or rings 47 (see Figs. 2, 3 and 6) are adapted to be placed bet-Ween the tumblers and .gears 41, as shown ice at the .right in Fig. 6, for example, or between the said tumblers 46 and ratchet wheels 45, as shown at the left in Figs; 2 and 6, for example. Obviously, the placing of the washer 47 determines the altitude of the tumbler 46 on the hub ofthe gear'41.

' This, as will hereinafter be noted, constisaid retainingr dogf 37 will yield and permit movemcntsoi the gear 32 in the direction ot' the arrow marked on Figs. 4 and 14, but will prevent reverse rotation thereof, bym frictional clutch action. r Thefloosc gen 1G34 has an upwardly projecting stud 39 (scc parti ulariy Figs. 6 and 14) that is cngagcablc i the free cndv of `the tall 37a to release the retaintutes means for changingI the order of the combination.

The lower gear, to wit, the spur geai'Bf-, through an intermediate spur pinion 48, is connected to a. spur gear 49 secured on the. lower end portion of an upright shaft.. 50. `ionrnaled in its lower end in the base 26 and atits upper end in the bearing plate 28.

An upwardly spring pressed flange clutch head 51 is secured to rotate 'with the shafts() but permitted a limited vertical movement 'thereon by a slot andpin coupling 5.2 (ses Fig. 2). The anofe of this clutch head 5i Lacasse f perforations 53n (see Fig. ll) formed in a disk-lilre member 511- that is rotatably adjustable on the shaft 50, but is thus caused to rotate with thesaid shaft. This disk 54 carries a cana projection or cam-acting element 55 (seeFigs. 4, 11 and 13) which, as shown,

is in the form of a roller-equipped stud. This stud 55 is voperated on the reversely beveled cam surface 56n of a sliding bolt 56 (see Fig. 13). This sliding bolt 56, in some forms of the lock might be the lock bolt itselifybut in the present instance, it is utilized as a carrier for an electric contact that constitutes a partofan electric circuit which is to be controlled, and which may be assumed, for illustration, to be the ignition circuit of an explosive engine used in 'an automobile. This slidingu bolt 56, as shown, is connected to the bearing plate 28"x by screw and slot connections 56b (see Figs. 2 and 11). Said sliding bolt 56 is yieldingly retracted or pulled toward the left by a coiled spring 57 (see Fig. 13). I

It Will now be understood that the sliding bolt 56 will be moved into a position to perform a desired function', such as to close an electric circuit (see Figs. 11 and 13) or withfdraw a-.bolt of'a door lock (see Figs. 16, 17 'and 1S), or with the latch thrust bolt (see Figs. 21, 22 and 23), when the shaft 50 and disk 54 are given the proper predetermined number of steps ol rotation' required to throw'the stud 55 into direct contact with the central ortion of the cana surface 56. Obviouslyt e' number of steps ot movement required to effect this result may be varied by adjusting the said disk 54 in its relation to the coupling head 51.

It will be noted, `that there. are in this de- Vice, asillustrated, two independent sets of gears, to wit, the. gears 41, 32, 33, 4S and e9, which may bev treated as the combination gears, and the ratchet wheels or segments L15 and gears 12 and 311 which may be treated as the releasing or restoring gears. Springs or other yielding devices will be provided for normally holding and for restoring-to normal positions both sets of gears. For thus f restoring or returning to normal or to zero position, the tumblers 46- andcombination gears, for illustration, a coiled spring 58 of the clock-spring?,` type, anchored at its outer end to a bracket 59 on the traine 28, and at its inner end is attached to the head of the coupling head 5l, or to any other part that rotates with the shaft/50, The means for returning the gears 42 and 341 to normal or zero position is illustrated only in F ig'. 10, and Vas there illustrated, comprises a coiled 'spring 60 suitably anchored at one end, to

bracket 44,.-01 otherwise, and at its other B5.

end,vattached to an arm 45 of one of the ratchet segments 45 and yieldingly holds said arm against a fixed stop 61 projecting from bearing plate lll. or otherwise. Obviously, since all of the ratchet wheels or segments 45 are in fixed relation to shafts t3 and the gears Ii2 and 3l which are geared or connected t'or simultaneous rotation, a device that restores one thereof to normal position will also restore the others to normal position. Here it may be stated that the ratchet' wheels 45 are not given complete rotations but are oscillated only to approximately ninety degrees, and hence, may all be segmental.

It has already boeninade clear that the several groups ot' axially alincd gears, ratchet wheels and tulnblcrs are located radially outward of and are cireuinlierentially spaced around thel projected axis of the fixed stud 31. For coperation with these circuniferentially spaced ratchet wheels and tumblers, l provide so-cullcd actuatingfingers carried by the oscillating free or lower end of the stem of a .so-called rocking actuator arm. This actuator arm comprises a stem 62 which, at its upper or outer end, has a knob 63 and below said knob, has a ful* crum sleeve 62n to which it is connected by longitudinal slot and pin connections 6l. that permits said stein to move axially to the desired extent through said sleeve 621L but holds the same against rotation in respect thereto.

mctrically opposite trunnions 61k that are oted to lugs 65 on the bearingT plate 23a. In this way, the actuator arm or stein' 62 is mounted 'on a universal joint, but, nevertl1cless, it is regulated in its xnoif'cments and' is restored from its.oscillatory movements to a central normal position by means ol a guide plate 66 which has guideslots 66n (sce Figs. 6 and 7) 'that radiate in Jfour directions. Vto wit, each from the projo/cmd axis of the stud 3l toward the projected axis ot' one of the oblique shafts To the lower or fri-c end ol the stem 62 is attached a sleeve-lilac head 6i' that is proA vided with four radially projecting' ratchet engaging fingers 68 and :four similar gear tumbler actuatingA Fingers 6), ior a purpose presently to bev noted. The head 67 is mounted on the stem 62 with freedom for slight oscillatory movement permitted by a. slot and pin connection 67a (sceFig. 6). A coiled spring 61") secured to the stein 62 and head 67 yieldingly holds thc saine in norlnal position. 0n the stem 62 is a guide collar 62" which, by axial moven'lents of the: stein 62, is adaptedl to be set either just above or just below the curved ,guide plates In Figs. 2 and 3, the numeral 70 indicates a curved `guard plate loosely This sleeve 62, by means of dia-` nietrically extended trunnions 6l, 1s pivoted to a fulcrum ruig 64, winch, 1n turn, by dia 4,. senese surrounding the stem 62 and serves to keep closed the enlarged openingin the sheil 27 through which the said stem works With sufhcient clearance vto permitl its re quired oscillatory movements. The loclt will sometimes .be used with the actuating theraised position. indicated byy dotted lines in Fig. 6. rl`his statement assumes that some ot the tumblers 46 are set in low and some 1n high positions. The above notedmovement arm or stem 62 set in an upright position, of the fingers 68V and 69 from position or at an angle, and it will sometimes be applied with the said stem normally set in a horizontal direction, as, for example, when the lock is applied to a` door. in any of these arrangements, it is desirable that yielding means be provided for normally holding the said actuating arm 11i its neutral position or alined :with the stud 31. Ilhis may be ample, by means of a multiplicity 'of spring fingers '2'1" secured to the gnideplates 66 in rectangular arrangement, each crossing one of the guide channels 66g. l

The operation of the lock so for described,

i is substantially as follows:

From what has been stated, it will be uny 'dorst/ood that the actuating lingers 68 and 69 may be given oscillatory movement in any one of four directions and may he raised and lowered from one position into another, makingr in all, eight successive combinations of movements in= the working ,of the lock mechanism, as here illustrated. rlhe combination is set, as desired, by giving the desired rotary and axial adjustments to the tumblers 46 and to disk 54. ln the proper Working of the combination, it is necessary Ato bringI the proper actuating fingers 69 into action on coperating tumblers 46 in the proper order, to wit, in an order that vwill cause the operative finger 69 toengage the cam surface and adjust the lug of the cooperating tumbler 46. For instance, if the operation in Working the lock, is properly Aperformed, the vfinger 69, that it thrust laterally by an oscillatory movement of the vstem 62 toward theselected tumbler 46, will engage the cam surface and lug of such cooperating tumbler 46 in the position shown in Fig. 8 by full lines, and will move the said `tumbler 46 tothe position shown in Fig. 9. y Under this movement. the cam surface of thesaid tumbler =l6 will carry the corresponding finger 68 clear of the teeth of the coperating ratchet 45, and when the actuator arm is returned to .normal or ncutral position, the said carni surface will still Prevent the said finger 68 from engaging the said coperatlng ratchet 45.` The working of the combination requires such l movements of the actuator arm will progressively engage fingers 69 with tumblers 46 which are in operative position, as shown in Fig. 8. To effect this engagement it will sometimes be necessary to oscillate theva-ctualtor arm or stem 62 in some one direction with thel fingers 68 and 69 lowered, as shown by full lines in Fig. 6, and it will shown in Fig. 8 to position shown in Fig. 9,-produces a slight oscillation. of the head 67 on the actuator arm or stem 62 against the tension 0i' the spring .671. Then by the proper operating manipulations, the 'stud 55 of the disk 54, operating on the cam surface 56a, will move sliding bolt 56 to itsv extreme position to the right, as illustrated in Fig. i3.' For example, this opera-tion may be one in which the said sliding bolt 56 will either lock or unlock a door, forl ex ample, or it may-be an operation in which r the sliding bolt 56 .will either close or open an electric circuit; This complete operation of the sliding bolt 56 can he made only by a 7 ating ratchet 45 and the said ratchet 45 will be given a step of movement against the tension of the spring 6.0. This movement of the ratchet l5, or any one thereof, Will be transmitted tothe gears 41 and 34 and such movement. imparted to said gear 34 Will.

throw its stud 39 against the free end of the tail 37a of the retaining dog 37 (see Figfll), and thereby positively release the said retaining dog from gear 32.- The spring 40 then temporarily latches the retaining dog 37 in its released positionv which permits spring 58 (see Figs. 2 and 4) operating through shaft 50 and gears 49, 48, 33, 32 and 4l, to instantly lrestore lall of' the tumlblers 46 to their normal or zero positions.`

J ust before the gear 32 reaches the extreme of its .backward movement to zero', its

lug 32a (see Fig. 15), striking the .bulgedA same in the difierent positions in which it will be set, step by stepunder proploperation of' the combination. A stop shoulder 72 on the disk 5l engages affixed Stop 72ato limit the backward rotation of the `com,- bnation gears to zero position (scc Fig. 4).

To restore the combination or locking parts to Zero or normal lock position after the combination has been properly/.operated to open or unlock the lock, it is only neces- Lacasse Preferably, a finger and tumbler movement performed aft-er the combination has been properly operated to unlock the lock, will be utilized to release the 'casing lock (see Fig. 3a). Such manipulation would cause one further step ot' rotary movement of the disk 54, thereby causing a pin 7 8 on -said disk'to engage one end of a thrust lever 74 that is pivoted to a latch plate 30 mounted to slideon the bearing plate 28, as already noted, and subject to springs 75. 76 .indicates a spring-pressed plunger or piston mounted in a suitable fixed bearing 1n position for engagement with the segmental end of the lever 74 and in position to be engaged by the sleeve 62 of the actuator arm 62 When the latter is moved -toward the same. lfVhen' the parts are in the position shown in Fig. 18, movement of the arm against the said spring plunger 7G will not perform any function, but when the lever 74 is moved by the last step of movement of the disk 54, the segmental end of lever 74 will be in position to be engaged by plunger 76, so that when moved by the above noted oscillation of the actuating lever (S2, the latch plate 30 will be moved toward the right in respect to Fig. 13, thereby disenaging the same from the lock lug 29 of case .shell 27, and this, of course, releases the said shell so that it may be lifted vfrom working position, provided, however, that the knob 68 first be removed from the stem G2. Pret'- erably, said stub is detachably secured to said stem bya pin 63 (see Fig. 2).

. coperating ratchet 45.

To prevent the above noted manipulation required to release the vcase lock, from 0perating'the ratchet releasedevice and there by causing the sliding bolt 5G to be returned to its normal position, a blank tumblerv This blank tumbler may b should be-used. be very much like the tumbler 48, but should not have a projecting lug. itsl function being' to prevent `finger 68 from engaging with the This blank tumbler may be applied in addition tothe Jtour regular tumblers that are used in working a combination. For example, one ot the said tumblers 46 might be made double-endcd with the lug omitted at one end.

ln the illustrations, Figs. 1 to 15, inclusive, the slidinv bolt 56, when at the extreme right, will press an electrical contact 77 Which is'carried thereby, into engagement with an insulated contact 78 on the trame .28, and thereby close a circuit 79 which alarm with the lock above described, and this, as illustrated, comprises as follows:

The numeral 8() indicates a small lever that is intermediately pivoted to a bracket 81 on the frame 28, (see Fig. 18), and care ries an electric contact 82 that is normally disengaged from, but is engageable With'aii insulated iix'ed electrical contact 88. These contacts 82 and 83 will constitute parts'of an electric circuit which will include also a bell or sional device of some character, not shown. ne endof this lever is connected to one end of a 'rod 84, the :other end of which is eccentrically pivoted to one of the above noted ratchets 45. The rod 84 has a headed end that Works freely through' the connected end of the lever 80, and that same end ofA the said lever is subject to a light coiled spring 80. The other end of the lever 80 is arranged to be engaged and held by the hook-'like end of a curved spring latch 85 that is normally sprung downward against a stop pin 86 on the sliding bolt 56.r lVhen the slidingbolt 56 is in its locked position shown in F ig. 13, ii an incorrect manipulation of the actuating stem G2 is made, in an attempt to work the combination, the ratehets 45 are operated and then, of course, the particular `ratchet 45, to which the rod 84 is pivoted, will be oscillated, and this will move the lever 80, so as to force its contact 82 into engagement with contact 83 and its free end into engagement with the hooked end of latch 85. Latch 85 will then hold the alarm circuit closed until,

by the proper Werking of the combination sliding bolt 56 has been moved to the right into unlocked position, as already described. Under movement of the sliding bolt 56 toward the right, pin 86, operating on the curved portion of latch 85, releases the same Vl'romthe lever 80, and permits spring 8OLl to then restore lever 80 to normal position shown in Fig. 13, thereby, of course, cutting out the alarm.

Figs. 1G to 20 illustrate a form of lock especially adapted for use as a door lock. lnthis form of lock, so-called a door lock, all of the parts from the actuating arm to the disk 54 and its crank stud 55, and including the ratchet release or restoring parts are, or lmay be, identical with those lllustratcd in Figs. 1 to 15, inclusive. In this arrangement, liowcver, the lock. bolt 87 which corresponds in some instances to the sliding bolt 56, is outwardly springqiressed by a spring 88 and is moved against the tension of said spring, or retracted, by the cam stud 55 of the disk 54, operatingon a bell crank 89. This bell crank 89 is suitably' pivoted to the 'frame 28, and that arm thereof, that is not engaged by the stud 55 is eneagcable with a stud 87 on the lock bolt 87 sce particularly Figs. lll and i8). licll crank 89 is also subject to a light coiled spring 89n which tends to normallyrl-` hold the same against a fixed stop 90. In a door lock, the knob 63 Will be at the outside of the door., -To operate or retract the lock bolt from the inside of the door, an arm 91 Within the case, is also engagea-ble with the stud 87 and is normally held against a fixed stop by a coiled spring 92. This arm 91 is on the angular;inner end' of'a shaft 93, which, at the inner side of the lock, has a linger piece 93, by means of which the same arm 91 may be moved against the tension of spring 92 to retract the "bolt 87, as stated. The burglar alarm attachment in this modified form of the lock, is much on the same plan as'that previously described and includes the same rod-84%. This rod 84 is connected to a bell crank 94 that carries an electrical contact 95 that is engageable with a coperating 2o electrical contact 96 on the lock bolt 8'?, when and `only when 'the said loch bolt is in a projected position shown in 16, .The numeral 97 indicates a spring latch on the lock bolt 87, which, when the lock holt is projected, will engage bell crank 94 and lock the same with electrical contacts 95 and 90 engaged until lock bolt 8T again retracted. The construction illustrated in Fin', 20 30 like that illustrated-in Fig'. 17, except that Athe outer end ot the lock bolt 87 is beveled and reversible. The lock illustrated in 21 to 25, inclusiveis designed as a loclr for the transmission of an automobile. in this form of the lock, all oil the parts from the actuating arm to the disk 54e and its cam stud 55, are, or may be, identical with those illustrated in Figs. l. to 15, inclusive, including, of course, the ratchet or release, or 40 restoring device. In this arrangement, the cam stud {i5-operates on an arm 98 on the upper end of a vertical lock shaft 99, which, nearits lower end, has ka lock arm 100. This lock arm 100 has a segmental free end that is engageable with the'peripheral channel -101 of a lock bolt 102 that is mounted to slide vertically. through the case and is yieldingly pressed upivard by a coiled spring 103. The lower end of this lockbolt in the construction here illustrated, is connected bya bell crank 104 and link 105, to some movable part of the transmission mechanism, such, for example, as to the lower end portion or gear parts of the shift lever z 100. The alarm device here shown, includes a bell crankA 107 that is connected to ythe rod 84 and carries an electrical contact 108 that is engageablevvith a iixed insulated electrical contact 109. In the position shown in Fig; 23, the alarm is in operating position, the contacts 108 and 109 being held engaged by the action of a spring-pressed dog 11.0 on one of the arms of the bell crank 107. Vllhen the arm 98 is moved outward and engages the dog 110 and moves the same so that its,

escasas -broad and liberal sense to include the progressively set elements upon Which the actu' yator arm and stem 62 operate when prop- 4crly manipulated.

The expression tumbler actuator is also used in a broad sense to include a device, which, by proper movement, will engage and operate the above noted elements or so-called tumblers and gears. The ratchets 515 illustrate one posslble form of tripping element, which, When moved by a proper manipulation .of the tumbler actuator will, through cooperating devices, cause the tumblers and associated connections to be restored to zero or neutral positions.'

What I'claim is: i

1.
